Add a very abridged version of SX150x driver from Linux. New, "pinctrl"
version of the driver was used as a base. As it was already mentioned
this driver supports very limited amount of the original functionality,
and the following are the features that were dropped:
- Interrupt support
- Support for any chip other that SX150x (due to lack of HW to test
with)
- Any pinctlr-like functions: pull-up/pull-down, open-drain,
etc. configuration

This patch changes the most part of mach-bcm2835 to mach-bcm283x. This
prepares to add RPi2 support which is a bcm2836. This patch changes the
Kconfig entry namens to BCM283X for drivers only. These drivers should
working the same in bcm2836.
While updating defconfig I added LED support/trigger option.

A 74x164 shift register can be seen as a SPI attached GPIO expander.
This adds a driver for those poor-man expanders based on the Linux
driver.

This driver provides common support for accessing
the CBUS FPGA I2C lines through the gpio library.
Additional i2c bitbang driver must be enabled
in order to use the functionality of the i2c controller.

This adds a DT only driver for the GPIO controller found on Marvell
Orion/MVEBU SoCs (Armada 370/XP, Dove, Kirkwood, MV78x00, Orion5x).

Rename "drivers/gpio.c" to "drivers/gpiolib.c".
Reason is for understand functionality of driver.
